25 June 2025 at 7:00 am · Check Out: 10 Hybrid & Electric Cars That Are Worth the Money in 2025 — Tesla Didn’t Make the Cut Looking at annual costs, Tesla Model 3’s calculation is $37.50 per month (250 kWh x 15 cents), equaling $450 yearly and the Honda Civic calculation looks like $113.63 per month (30.3 gal x $3.75), equaling $1,363.56 yearly. This means that across the country, the savings go to Tesla at $76.13 a month, which equals $913.56 per year. State Fuel Math To further illustrate the cost comparison between a Tesla and Honda Civic, Nagle analyzed two states: California, which has a high-cost market for transportation expenses and Florida’s lower-cost region for fuel. ADVERTISEMENT In California, electricity costs on average 33 cents per kWh and gasoline is $4.78 per gallon. Examining annual vehicle costs in the state, the Tesla Model 3’s bill comes out to $82.50 per month (250 kWh x 33 cents), equaling $990 a year, while the Honda Civic is $144.08 per month (30.3 gal x $4.78), equaling $1,728.96 a year. This means the Tesla has a savings of $61.58 a month or $738.96 per year. Florida, on the other hand, has average costs of 16 cents per kWh for electrics and $3.08 per gallon for gasoline. Factoring the yearly vehicle costs in Florida would have a Tesla Model 3 amounting to $480 a year based on $40 per month (250 kWh x 16 cents) and a Honda Civic at $1,119.84 a year coming from $93.32 per month (30.3 gal x $3.08). Again, the Tesla wins with $53.32 per month, adding up to $639.84 a year. Where Do the Numbers Land? In every scenario-national average, California’s high-cost market and Florida’s lower-cost region — Nagle had some insights to share. “The Tesla Model 3 substantially outperforms the Honda Civic in terms of fueling costs. Even with California’s significantly higher electricity prices, Tesla remains the cheaper choice monthly and annually,” Nagle said. “This highlights a key advantage of EV ownership: regardless of location, driving electric consistently costs significantly less than fueling a gasoline-powered vehicle,” he added.
